An Austrian scientist once studied what makes us find something cute. The research showed that our brains are basically hardwired to find things like large eyes and small round bodies adorable. In other words, it’s basic science that looking at baby animals will make you feel happy! If you are ever feeling sad or low, just seeing a little duckling, piglet, or even a baby sloth is a surefire way to make you smile.
